LOCOMOTIVE PROVIDED WITH CONDENSERS.

Application filed August 26, 1922. Serial No. 584,527.

To ('17! whom it may concern:

Be it known that I, FREDRIK LJUNG- s'rnon, chief engineer, a subject of the King of Sweden, residing at Lidingo-Brevik, Sweden, have invented certain new and useful In'iprovements in Locomotives Provided with Condensers, of which the following is a specification.

In locomotives it has previously been proposed to provide them with condensers located in differentplaces on the locomotive. It is well-known to cause the re-cooling part of the condenser to co-operate with a steam accumulator operating under vacuum, it being necessary in such case to locate the condenser along the whole width of the locomotive. On account thereof the condenser has to be placed in front of or behind the steam boiler. In this case the air-cooled condenser together with the appertaining steam accumulator is preferably placed behind the steam boiler, counted in the running direction of the locomotive, the driving aggregate of the locomotive being preferably situated at the fore part of the condenser. In such case the condenser aggregate may be provided either on the same carriage as the steam boiler ot the locomotive or on a separate carriage running after the boiler carriage. It the condenser be located behind the steam boiler the first named will obstruct the outlook rearwards, and owing thereto the locomotive can run i one direction only, that is to say with the steam boiler and the drivers cab in front of the condenser, which however is unsuitable particularly in case of small locomotives, for instance for district trains and shifting.

This invention the object of which is to prevent said inconveniences relates to locomotives provided with condensers and in which the drivers cab is located between the condenser and the steam boiler of the locomotive, the invention consisting in that the condenser is placed above a receptacle appertaining to the same at such a height in relation to the floor of the drivers cab that tree outlook rearwards can be obtained from the drivers cab through a channel provided between the condenser and the receptacle.

The accompanying drawing illustrates diagrammatically a locomotive constructed according to the invention. Fig. 1 is in part a side view thereof and Fig. 2 a section through the drivers cab on the line A-A in Fig. 1.

Referring to the drawing, 1 designates the steam boiler, 3 the condenser, 4; the accumulator operating under vacuum and 2 the driving engine, all said parts being placed on the same carriage. The drivers cab 5 is located between the steam boiler 1 and the condenser device 3, 4, and the driving aggregate 2 is provided in a. compartment between the drivers cab 5 and the condenser. The air-cooled part 3 of the condenser is located above the steam accumulator 4: operating under vacuum at such a height as is permitted by the load gauge, a channel thus being formed allowing tree outlook rearwards in the direction of the arrow 12. The floor 13 of the drivers cab is generally located at a certain distance above the driving wheels. In the present case however the floor is so arranged that the driving wheels enter into caps 14-, Fig. 2, provided on the floor for the purpose of obtaining free outlook rearwards through the channel formed between the air-cooled part 3 of the condenser and the receptacle 4. As apparent from Fig. 2, the rear wall of the drivers cab is provided with windows 15. If the floor of the drivers cab be located at a greater height above the driving wheels than is supposed above, the air-cooled part 3 of the condenser is also raised to the extent allowed by the load gauge, free outlook being obtained even in this case below the air-cooled part of the condenser.

\Vhat I claim as new and desire to secure by Letters Patent ot' the United States is 1. In locomotives provided with condensers and in which the drivers cab is sit uated between the condenser and the steam boiler of the locomotive, an arrangement chara-cterized by the condenser being situated above a receptacle appertaining to the same at such a height in relation to the floor of the drivers cab that free outlook, real-wards, is obtained from the drivers cab beneath the condenser.

An arrangement according to claim 1,

characterized by the driving Wheels of the ers cab being provided with Window or winlocomotive entering into caps on the floor dows.
